Title: Improvements in the production of slit reels of flexible sheet material
Inventor: SAMWAYS BRUCE
IPC: D06H7/00
Filed: 1953-06-11
Abstract: 761,134. Feeding webs. BRITISH CELLOPHANE, Ltd. June 4, 1954 [June 11, 1953], No. 16147/53. Class 100(1) A web 11 of flexible sheet material, e.g. polythene or cellulose acetate, is unwound from a roll 14 which is continuously reciprocated in an axial direction within adjustable limits defined with respect to longitudinal slitting devices (not shown) such that when the web 11 is rewound portions of increased thickness are not spaced directly above one another, but are laterally offset. Longitudinal slitting devices are positioned in planes 2 and 7 in order to trim the marginal edges of the web 11. In one embodiment, jets 15 and 17, supplied with compressed air, are arranged above boxes 16 and 18 respectively. The boxes 16 and 18 are connected by pipes 20 and 21 to a bellows 26, 27 which operates a valve 22 which admits liquid under pressure from a pump 122 to a cylinder 23 having a piston connected by a coupling 24 to the axle 25 of the roll 14. When compressed air from the jet 15 reaches the box 16, due to movement of the edge 12 of the web 11 moving to right, the bellows 26, Fig. 3, is inflated to rock an arm 28 about a pixot 29, thus lifting a link 40 pivoted to a link 41 having pivots 42 and 44. A wheel 45 carrying a flap 46 is given a sudden counterclockwise rotation due to a spring 47 when the line joining pivots 43 and 44 is positioned above the pivot 42, such that an aperture 30 is closed. As a result a vacuum pump 33, Fig. 2 is connected to the valve 22, such that liquid is admitted to the right hand side of the cylinder 23, thus causing movement of the axle 25 and roll 14 to the left. When the edge 13 of the web 11 passes beyond jet 17 the valve 22 is operated in a similar manner by inflation of the bellows 27 to admit liquid to the left of the piston within the cylinder 23. Thus, the roll 14 is continuously reciprocated between limits defined by the distance apart of the jets 15 and 17 which may be adjusted in known manner. In a modification, the arm 28, Fig. 3, operates the valve 22, Fig. 2, by a mechanical linkage. Other detectors such as mechanical contacts, electrical contacts, vacuum or compressed air arangements in which the web edge closes an aperture, photo-electric cells, and capacitative 'arrangements in which passage of the web between condenser plates varies the capacitance of the condenser, may replace the boxes 16 and 18 and air jets 15 and 17. A servomotor actuating the roll 14 may be actuated by hydraulic, pneumatic or electrical means. Specifications 462,960 [Group XXIX], 687,932 and U.S.A. Specification 2,269,884 are referred to.

Title: Preparation of free-flowing flaked benzene hexachloride
IPC: C07C23/12
Filed: 1956-05-25
Abstract: Flaked benzene hexachloride is made by flaking molten benzene hexachloride, subjecting a thin layer, i.e. a layer having a thickness of between 1 and 3 inches, to a cooling atmosphere, preferably having a temperature between 50 DEG  F. and 120 DEG  F., for at least 40 minutes and packaging the product.  The preferred process, which is described with reference to drawing, comprises continuously applying molten benzene hexachloride to the periphery of a rotating cooling drum, scraping benzene hexachloride as flakes from the surface thereof, distributing the flakes on a moving surface such as a moving belt and moving the surface through a cooling atmosphere for at least 40 minutes.

Title: Improvements in duplex radio aerial systems
IPC: H04B1/10
Filed: 1934-05-31
Abstract: 424,239. Wireless signalling ; aerials. AMY, ACEVES, & KING, Inc., 11, West 42nd Street, New York, U.S.A.-(Assignees of Amy, E. V., and Aceves, J. G. ; 11, West 42nd Street, New York, U.S.A.) May 31, 1934, No. 16252. Convention date, Dec. 22, 1933. [Class 40 (v)] Long and short wave signals are received alternatively or simultaneously on a common aerial through a down lead which is free from interference by local sources of induction. The whole of the aerial A, All is used for the long waves, the signal currents being transferred through a transformer T so that they flow serially through a double transmission line D, D1 to a branched coil T11 feeding the long-wave receiver R1, or to the coil T1111 feeding a combined long and short wave set R11. Short-wave signals are fed by direct coupling from the point B of the dipole aerial A, A1 through a condenser C and downlead D to the coupling-coil T1 of the receiver R (and to the parallel coupling-coil T111 of the receiver R11) and back through the return lead D1 to the point B1. The impedance of the coils T11 and T111 is sufficient to exclude these currents from the long-wave receiving circuits. The main aerial-to-earth circuit for the long-wave aerial is completed from a centre tapping on the transformer T, through the twisted downleads D, D1 in parallel to earth at G through a centre-tapped coil L3. Inductive " pick-up " currents pass through the downleads D, D1 in parallel, and are therefore balanced out in the receiving circuits. The secondary of the transformer T may be directly earthed through a third winding, which is screened by the leads D, D1 ; and auto-transformer coupling may be used. Separate aerials, set at right-angles, may be used for the long and short wave signals, Fig. 4, (not shown). If the input transformers to the sets are loosely coupled, different sets may be tuned to different frequencies on the same wave-band without mutual interference.

Title: Production of granular, non-dusting sodium metasilicate
Inventor: MOCKRIN ISADORE
IPC: C01B33/32
Filed: 1956-05-25
Abstract: Finely - divided substantially anhydrous sodium metasilicate is blended with sodium metasilicate penta- and/or hexa-hydrate at a temperature between the melting points of the hydrated and the anhydous metasilicates, to obtain a substantially anhydrous non-dusting granular product.  Preferred temperatures are 90 - 250 DEG  C.; preferably 15 - 45 % by weight of the hydrate is used. Blending (which in the example is performed in a drum rotating about its horizontal axis), is preferably carried out in an apparatus open to the air and a gas, preferably air free from carbon dioxide, may be used to sweep out the steam.  When small batches of material are treated, the presence of sodium hydroxide should be avoided.  The bulk density of the product increases as the rate of heating, especially between 70 DEG  and 150 DEG  C., is reduced, and as the proportion of hydrated silicate is increased.
